Green Roofs in Singapore

Green Team at Green Roof Technology, - Monday, December 23, 2013

In Southeast Asia. one island-city is rising above the rest. Singapore has been working on a greening blueprint of the city since 1992. Their ultimate goal: to evolve into a city within a garden! With approximately 272 square miles and 4.6 million people, the biggest challenge faced is space.

 

With 148 acres of vegetated roof space, Singapore has already made it a priority to promote green space. Careful planning has helped to conserve 9% of their total land mass to parks and nature reserves. In 1986, only 36% of Singapore was green space, compared to almost 47% known today.

 

The Parkroyal Hotel, opened earlier this year, is covered in green roofs and walls. Totaling 15,000 square meters of green space all together.

The School of Art, Design and Media at the NanYang Technological University in Singapore sports a curving green roof, giving the building a sleek look. As buildings continue to green, Singapore will grow closer to their goal of becoming a garden with a city nestled inside rather than a city with a few gardens.

Many companies have been involved with the green in of Singapore. To name one, Verditecture LTD, has been in the building and construction industries since 2003. A partner of Optigreen, they have been focusing most of their time on skyrise greenery. 

Yamato Cockroach Found in NYC High Line

Green Team at Green Roof Technology, - Tuesday, December 10, 2013


Periplaneta japonica, otherwise known as the Japanese cockroach or Yomata cockroach, was recently found in the United States for the first time.  Exterminators working on the High Line in New York City found the unusual insect around stones and planting material.  Many of the ornamental plants installed on the High Line were imported from Asia and it likely that the some of these plants were infested with eggs or nymphs of the Japanese cockroach.

The Japanese cockroach,  unlike the American cockroach, Periplaneta americana, is adapted to cooler northern climates.  It has a flexible univoltine or semivoltine (one or two year) life cycle, depending on the timing of its hatching, and is unusual in being able to spend two winters as diapause nymphs before reaching maturity.

Nymphs have been observed in the wild hibernating in sub-freezing temperatures during winter months in snow-covered habitats. Overwintering nymphs were able to survive laboratory supercooling experiments in the -5 °C to -8 °C temperature range, enduring twelve hours of tissue freezing, as well as recover from burial in ice.

The Japanese cockroach is primarily an outdoors species, though some populations are adaptable to living indoors in houses and buildings where food is stored, prepared, or served.  This is in contrast to the American cockroach that is not adapted to living outdoors in the winter and will immediately move indoors when the cold weather begins.
